Sewell’s sources are eclectic: they range from a philosophical tract by Diderot to the statutes of mutual-aid societies, from artisanal and working-class newspapers to quasi-official reports on the conditions of the working poor, from intellectual tracts on socialism to workers’ poetry. All these comprise “a set of interrelated texts that demand close reading and careful exegesis” (11-12). Sewell rereads and reinterprets these texts with an eye for their linguistic and historical logic. The “socialist vision of labor” was a logical development of certain fundamental Enlightenment concepts, but that logic was pushed forward not so much by intellectual as by social and political developments, in particular, by the revolutionary “bursts” of 1830-34, 1839-40, and 1848-51 (278). In attempting to explicate this “dialectical logic,” Sewell synthesizes an extensive published literature on French labor, and he effectively underlines the importance of paying very close attention to what people in the past said, sometimes indirectly, about what they were doing.
